RETORT OF THE DIRECTOR AND STATE GEOLOGIST Pl45 



This statement of red slate production includes the combined 

 outputs of the Flaherty and O'Brien quarry at Hatch hill and 

 the two quarries of the National red slate co., which were pur- 

 chased by the Penrhyn co. Except for the months of January 

 and February, the statement of slate other than red includes the 

 product of the Jones & Williams quarry, at Jamesville, together 

 with that of the Penrhyn quarries. 



Near the Penrhyn mill is a small red quarry, located on the 

 same bed as the Mettowee quarries, but now idle. 



A mile east of the Penrhyn quarries on the opposite side of the 

 valley are the quarries of the Eagle red slate co. These are the 

 most northerly quarries on (what the quarrymen call) the " Gran- 

 ville and red belt w * There are four large openings, but all 

 except the most northerly are idle. This quarry is about 250 

 by 90 feet in area and 00 feet deep. The cleavage dips 45° e 

 5° s and strikes s 5° w. The east wall is unfading green slate, 

 and on the west wall, which is a smooth cleavage surface for 

 half the length of the quarry, is a most unique color effect. The 

 upper 25 or 30 feet of this surface is bright red, which gradually 

 changes to the typical unfading green below that depth. A 

 specimen of this material 6 inches long, collected for the museum 

 from the point where the change in color occurs, shows the 

 tendency toward red at one end and green at the other. 



Both red and unfading green slates are quarried here in large 

 quantities. The entire output is made into roofing material. 



A half mile south of the Eagle quarries are those of the Nixon 

 red slate co., now owned by E. J. Johnson & Co. There are 

 three openings, the largest of which is about 250 by 100 feet in 

 area. The cleavage dip is 36° e 10° s and the strike is s 10° w. 

 Both red and unfading green roofing slates are quarried. The 

 large quarry was operated during the summer of 1898, but shut 

 down in the fall, owing, it is said, to financial difficulties. 



South of the Nixon quarries and north of the village of Gran- 

 ville are the two red quarries of the Empire red slate co., and 

 one belonging to Andrew Norton. These are idle.
